span_context: Span context. If missing, the active context is used,
if any.
Value
The histogram object itself, invisibly.
Details
Usually you do not need to deal with otel_histogram objects directly.
histogram_record() automatically sets up a meter and creates a
histogram instrument, as needed.
A histogram object is created by calling the create_histogram() method
of an otel_meter_provider().
You can use the record() method to update the statistics with the
specified amount.
